WebbThe results showed that, using immobilized LZ-M, MNZ was completely removed, and the degradation efficiency of wastewater's chemical oxygen demand (COD) was increased from 11.7% to 83.31%. The extracellular polymer and ROS levels indicated that MNZ's toxicity on AAS was reduced. WebbConventionally, lower sludge production is considered to be an advantage of anaerobic treatment. However, in the present comparison, it is seen that the total quantity of sludge produced from UASB-based CETP is higher (1.4 t/day/MLD tannery efﬂuent) compared with ASP-based CETP (0.8 t/day/MLD tannery efﬂuent). This is undoubt-
